cp myfile.iso /dev/sdb
compared with this one: dd if=myfile.iso of=/dev/sdb bs=32M
because implementation of cp have a fixed buffer, so if the amount of data is big and the disks fast, using cp you are calling more read() and write() syscalls than necessary, slowing down the copy process.EDIT: I've read the article: "is the size of a two-pence coin", so how many fraction of ug of Co2 can absorb of the "Around 35 billion metric tons of CO2 are released into the atmosphere per year" ? But the last part is fantastic: "The results from Temprano's contribution help narrow down the precise mechanism at play inside the supercapacitor when CO2 is absorbed and released", so when the battery discharge release the Co2 again , right? So what is the point of the whole article?

so the affirmation that "Nuclear Fusion Is Close Enough to Start Dreaming" could be other speculation of the press not supported by facts. Obviously I hope to be wrong.
